Application filed December .13, 1923. Serial No. 680,414.

To all whom it may concern:

Be it known that I, JAMEs MITCHELL, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of WVisconsin, have invented certain new and useful Improvements in Washing Machines; and I do hereby declare that the following is a full, clear, and exact de scription thereof.

This invention relates to washing machines and is particularly directed to a rotor for washing mzmhines.

Objects of this invention are to provide a rotor which-is composed of a plurality of identical partitions and a plurality of identical plates adapted to be bolted between such partitions, and to provide a rotor in which an exteriorly opening pocket construction is-provided, which notonly acts as a water receiving pocket but also as an internal rib and as a reinforcing element for the rotor.

Further'objects are to provide a rotor for a washing machine which is made of a plurality of duplicate parts so that any desired length of rotor may be provided without in any way altering the construction or necessitatmg new and distinct parts.

Further objects are to provide a rotor having circular partitions and a cylinder wall or peripheral portion provided with internal corrugations and to provide outwardly opening channel shaped reinforcing members which are also corrugated on the portion presented towards the interior of the rotor-so that the material within the rotor is given a scrubbing action as well as a washing action.

An embodiment of the invention is shown in the accompanying drawings, in which Figure 1 is a vertical sectional view through themachine with parts broken 'away to more clearly illustrate the construction.

Figure 2 is a side elevation partly in section of the machine.

Figure 3 is a detail corresponding to a ed to be bolted to the end walls of the rotor, as shown in Figures 1 and 2.

The rotor comprises a plurality of par titions such as the end partitions 5 and one or more intermediate partitions 6. These partitions, it will be-noted, from Figure 2, are identical in construction and are provided with a peripheral flange '7 which not only braces such partitions but also provides a ready means for joining the partitions to the cylindrical portions of the rotor. Between the partitions a plurality of hollow ribs are provided which have bottom portions 8 and walls 9 and side walls 10. All of the walls are provided with longitudinally extending corrugations 11 and the bottom is provided, in addition to the corrugations, with a plurality of apertures 12. The end walls 9 are bolted directly to the faces of the partitions, and certain of the bolts as, for instance, those indi cated at 13 in Figure 2, are of relatively greater extent and directly engage adjacent end walls of successive channel shaped ribs. These ribs are regularly spaced as maybe seen from Figure 1 and constitute outwardly open pockets to receive and elevate water and also to act as braces for the rotor. In addition to thesethey provide obstructions or projections over which the clothes are adapted to slide upon operation of the apparatus.

A plurality of curved plates 14 are bolted directly to the inner faces of the flanges 7 and their ends are bolted to the inturned,

of the plates 14. These plates, as will be seen from Figure 1, are located adjacent their ends between the inwardly turned flanges 15 of the ribs and the flanges 7 of the partitions. These circular plates are all of similar construction and are provided with a plurality of apertures 16 therethrough and with groups of transverse corrugations 17. These corrugations 17, it will be noted from Figure 1, are arranged in groups and the apertures 16 are located between successive groups. This construction has been found highly advantageous in washing machine construct-ion as the clothes are not allowed to completely seal the openings 16 and thus clog the machine, but are spaced from such openings by the successive groups of corrugations, and in addit1on to this, these transverse peripherally arranged corrugations have a scrubbing action upon the clothes when the device is rotated.

It will be seen from the construction thus 'far described that a pluralityof co-mp-art-.

. one end hinged to brackets 19 provided with upstanding apertured ears 20 which receive the pintle of the doors 18. It is prefer able to mount the brackets 19 for each of the compartments within a hollow rib, as shown in Eigures 1 and 2, thus avoiding any projecting obstruction. The other end of the door member 18 is provided with a flange 21 which fits over the inwardly turned flange of the adjacent hollow rib. At a point spaced slightly inwardly of the free edges of the door member, a depressed portion or channel 22 is formed and is provided with apertures 23. A plurality of resiliently urged plungers 24 are mounted within these depressions and are carried within suitable apertures formed in webs 25 ar ranged transversely of the depressions 22,

as may be seen from Figure 2. The outer ends of these plunger-s are adapted to fit beneath the flanges 7. of the adjacent partition. I 1

It will be seen that any desired length of rotor may be secured by merely bolting in regular succession the circular partitions, the spacing and strengthening channellike ribs and the curved plates 14. It is to be particularly noted that these channel shaped ribs provide a highly rigid brace or reinforce for the composite rotor so that there is no danger of the rotors twisting in operation or of the sagging of such rotor although the rotor may be formed of a large numberof successive comp artments.

Upon rotation of the rotor, it will be 1,524,eae

noted that the pockets formed within the ribs pick up the water and elevate it, thereafter allowing the water to flow through the apertures 12 into the rotor.

In addition to this, water is picked up interiorly of the rotor to a certain extent by these inwardly projecting ribs and also the clothes contained within the water will beelevated and violently dropped back into the lower portion of the rotor between the ribs. It is intended that the casing shall be filled with water to 'apoint slightly beyond a horizontal diametrical plane. It is further to be noted that inasmuch as the partitions are all of the identical construction and the plates 14 are also of identical construction that it is a simple matter to provide *a rotor of any desired length by bolting successive units to gether to form the requisite length of rotor.

It is further to'be seen that the corrugated inner surface of the rotor provides a scrubbing action for the clothes and in addition to this. these corrugations extend completely around the interior of the rotor and along the interior faces of the hollow ribs.

Although the invention has been described in considerable detail, it is to be understood that the invention may be variously embodied and is, therefore, to be limited only as claimed.

I claim:

A washing machine comprising a cylindrical casing, a cylindrical rotor substantially.

filling said casing and revollubly -mounted therein, said rotor comprising a series of circular partitions having marginal flanges, a plurality of hollow outwardly opening ribs mounted between succeewive partitions, said ribs being provided with apertures there through, and a plurality of circular plates bolted to said flanges and to said ribs, said plates being corrugated and aperture/d.

In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee. in the county of Milwaukee and State of Wisconsin.

Jae. MITCHELL.
